ADAPTATIONS
Mrs. Pigott’s 5th Grade Science
LIFE IS EXTREMELY DIVERSE
ALL LIFE ON EARTH ARE ALIKE IN SOME WAYS
•
They all need
•
•
•
•
Food
Water
and gasses from the air
They must meet these needs in many different kinds of places.
•
•
Rain forests, deserts, oceans, lakes and other places
Each plant or animal has features that help it survive in its ENVIRONMENT,
or surroundings.
WHAT ARE ADAPTATIONS?
•
Any feature that helps a living
thing survive in its environment is
an adaptation.
•
Each living thing is born with its
adaptation.
•
Adaptations DO NOT develop
during its lifetime.
•
The plants and animals that are
best suited to the places they live
are most likely to survive and
reproduce.
•
•
This is know as “survival of the fittest”.
They pass their helpful adaptations on
to their offspring (children).
•
What might have caused zebras
to have stripes, but NOT horses?
ADAPTATIONS IN LAND ENVIRONMENTS
•
Rain Forests (lots of water
and plants)
•
Plants need sunlight to make
food, but it is often blocked by
other plants because they grow
so closely together.
•
•
So, many rain forest plants have
long trunks and broad leave, to
gather as much sun as possible.
Animals adapt too. Howler
monkeys use their tails to grab
branches, and sloths use long
claws to do the same
LAND ENVIRONMENTS (CONTINUED)
•
In Desert, water is scarce.
•
To survive without very much
water, cactuses have roots
that spread out near the
surface. When the rain falls
they soak it up quickly.
•
•
Plants loose water through their
leaves, which is why cactus have
needles that also protect them
from animals.
Lizards and snakes have scales
to keep them from loosing
water through their skin.
LAND ENVIRONMENTS (CONTINUED)
•
The Artic Tundra is in the
northern polar region.
It has little rain.
• It is not dry, but it is cold.
•
•
Plants in the tundra grow only
a short time each year.
•
•
They are small and close the
ground.
Most animals have thick fur,
layers of fat or both.
•
Animals in the tundra often
hibernate to conserve their
energy. (which is also an
adaptation)
ADAPTATIONS IN WATER ENVIRONMENTS
•
There are two main water
environments.
•
•
Saltwater and Fresh water
Oceans contain most of the salty
water.
•
Most of the plant life in the ocean is
called phytoplankton.
•
•
They use sunlight to make food and so
float near the surface of the ocean.
Fish and Whales are two examples of
closely related, but different groups
of saltwater animals.
•
•
•
Both have streamlined bodies to move in
water.
But, Fish breath with gills
And, Whales and dolphins, being
mammals, must breath air
WATER ENVIRONMENTS (CONTINUED)
•
Tide Pools are pools of
ocean water left on the
shore when the tide goes
out.
•
Animals that live in tide
pools have adaptations that
keep them from being
swept back out to sea.
•
Can you identify the
adaptation used by each of
these tidal pool residents?
WATER ENVIRONMENTS (CONTINUED)
•
Rivers and lakes contain the
majority of the LIQUID fresh
water. Most of the world’s
fresh water is frozen in
icebergs.
•
•
One adaptation of a freshwater
plant can be seen in the water
lily. It has wide leaves that float
on top of the water and a long
root that reaches to the soil at
the bottom.
Freshwater fish are very much
like saltwater fish in that they are
streamlined and breath through
gills.
OTHER ADAPTATIONS
•
Camouflage use of coloring
and or patterns to help living
things blend into their
environment.
•
Migration is when animals
travel long distances to be
able to find food and stay
warm during cold seasons.
EXIT TICKET
•
When an animal hibernates
what does it do?
•
•
•
•
A. store food
B. stays active
C. saves energy
D. moves to a warmer place
•
The snowshoe rabbit lives in
an environment that is cold
and snowy during winter.
The rabbit loses its brown fur
in fall and grows white fur.
What is this adaptation
called?
•
•
•
•
A. camouflage
B. hibernation
C. behavior
D. migration
